Transient Radiated Fields from Sources Located on a Planar Surface.

Abstract

Expressions for the transient radiated electric fields of a planar array of sources are developed for elements having known field distribution, as well as time delay, located on an infinite, perfectly conducting, ground plane. The analysis of such arrays is based on a Green's function approach to the electric vector potential problem. Planar arrays of two-dimensional sources are analyzed in this manner using numerical computation of the appropriate superposition integrals and the related space-time Green's function. Plots of the time history of the radiated far-fields are presented for various configurations and observation angles for constant amplitude distributions on each array element. (Author)
